Johnson in Minneapolis

I am seaching for Violet Johnson. Her mother was Hildur E Johnson, born May 17 1887 in Sweden, died May 28 1973 in Hennepin (8124 Mount Curve Blvd., Brooklyn Park, Minneapolis). Violet was married to Henry Johnson, listed in her mothers death certificate, living on the same address. Hildur camed to US in 1910, mothers maiden Olson (but also Larson).

I have not found Violet's birth/death dathe or place (or father), or her husbands birth/death dates. They had children, by the obit, which did not give anything more.

Can this be her? (from mnhs.org) JOHNSON, VIOLET E.? Date of Birth:27 NOV 1911? Place of Birth:OUT OF STATE ?Mother Maiden Name:OLSEN CERTID# 1991-MN-012138?? Date of Death:04 MAY 1991? County of Death: HENNEPIN
